Lighting fixture



G. MANSSON LIGHTING FIXTURE May 15, 1 67 2 SheetsSheet 1 Filed NOV. 27, 1964 ATTORNEYS United States Patent York Filed Nov. 27, 1964, Ser. No. 414,232 3 Claims. (Cl. 2404) This invention relates to the art of lighting fixtures and more particularly to lighting fixtures having an adjustable concealed mount.

As conducive to an understanding of the invention, it is noted that where, for example, it is desired to provide illumination for dressing tables or the like, in which a mirror is positioned at the rear of the dressing table, and proper illumination should come from both sides of the mirror, the arrangement of light bulbs on opposite sides of the mirror raises numerous problems. Thus, where wires must be run to the separate light bulb sockets, a multiplicity of wires are required which are unsightly and are subject to tangling. Furthermore, where separate lines are run to each light bulb socket, a plurality of plugs are required to effect connection to the generally available baseboard outlets.

Other problems arise in the provision of light on opposite sides of a mirror or dressing table in that it is generally desired to provide for adjustment of the positioning of the light bulbs to effect the desired illumination.

As a general rule, such dressing tables, or mirrors are sold without accompanying lighting fixtures, and the user must thereafter provide the desired illumination. Utilizing conventionally available lamps positioned on the dressing table creates a cluttered situation and where the lighting fixtures are permanently mounted on the wall of the room on each side of the mirror, unless the wiring is concealed in the wall itself, which requires the services of a plasterer and an electrican, with attendant cost, unsightly wires will be present and in any event the mirror cannot readily be moved.

It is accordingly among the primary objects of this invention to provide a lighting fixture particularly adapted for positioning in conjunction with a dressing table or mirror to provide for desired illumination thereof without need for utilization of the surface area of the dressing table and without need for the services of a skilled tradesman in the installation thereof and which will be devoid of unsightly wires.

Another object of the invention is to provide a lighting fixture which affords illumination from opposite sides of a table or mirror.

It is also an object of the invention to provide a universal lighting fixture in which the positioning of the illuminating bulbs is subject to selective adjustment depending on the size of the mirror.

A further object of the invention is to provide a lighting fixture having a plurality of light bulbs, the energization of which may be accomplished by use of a single power line adapted for connection by means of a single plug to the generally available baseboard outlet.

According to the invention these and other objects which will become hereafter apparent are achieved by forming an elongated substantially rectangular base plate with a slide channel rigid therewith and extending the length thereof. A wire concealing channel is also preferably provided on the base plate parallel to the slide channel and spaced therefrom.

Positioned in each end of said slide channel and extending outwardly therefrom is the arm of a bracket member dimensioned to slide freely in the associated channel, each of said arms having its free end bent out of the plane of the base member and carrying a bulb socket. The electrical leads of the sockets extend through a slot 3,320,4l3 Patented May 16, 1967 in the bottom of the slide channel into the wire concealing channel where they are connected to an electric cord that extends through an opening in the floor of said wire concealing channel, the free end of the electric cord having a plug adapted to be inserted into the conventional baseboard receptacle. Preferably, a set screw is provided in the slide channel to permit setting of the bracket arm at any desired position.

In use, the base plate is preferably secured to the rear of the mirror to be illuminated. Thereafter, by inserting the plug at the free end of the electric cord into a suitable electrical outlet, and positioning of the socket supporting bracket arms as dictated by the mirror width, illumination may be obtained of the mirror and of the table in connection with which the mirror is employed.

A feature of the invention resides in the fact that all necessary wire connections and excess wire may readily be hidden by the wire concealing channel on the base plate and any loose wires are protectively enclosed in said channel.

A further feature of the invention resides in the fact that desired spacing between lamp bulbs may readily be effected as desired by the user.

A still further feature resides in the fact that by reason of the shallowness of the base plate and associated channels, the mirror may still be hung closely adjacent the wall.

in the accompanying drawings 'in which are shown one or more of various possible embodiments of the several features of the invention,

FIG. 1 is a perspective view of the lighting fixture mounted behind the mirror of a dressing table,

FIG. 2 is a sectional view taken on line 22 of FIG. 1,

FIG. 3 is a sectional view taken on line 3-3 of FIG. 2,

FIG. 4 is a sectional view taken on line 4-4 of FIG. 2 showing a candelabra type of lamp socket mounted on the free end of the bracket arm, and

FIG. 5 is a fragmentary detail view taken along line 5-5 of FIG. 3.

Referring now more particularly to the drawings, like numerals in the various figures will be employed to designate like parts.

As shown in the drawings, the lighting fixture comprises an elongated substantially rectangular base plate 12 having a slide channel 13 formed thereon extending the length thereof. Slide channel 13 has a top wall 10 extending laterally outward from the base plate 12 with a downwardly extending flange 15 at its outer edge defining the side wall of the channel and lying in a plane parallel to and spaced from said base plate 12. A lip 15 extends inwardly from the lower edge of flange 15 and cooperates with an outstanding lip 17 on base plate 12 to define the lower limits of the slide channel 13 as best seen in FIG. 3, the space 31 between the lips providing a passageway from the electric wires W.

Positioned beneath the slide channel and extending parallel thereto is a Wire enclosing channel 14 which comprises an elongated substantially rectangular strip 21 extending laterally outward from base plate 12 and which has an upstanding flange 20 at its outer edge defining the side wall of such channel and illustratively lying in the same plane as flange 15, the strip 21 having wire passing apertures 22 therein, illustratively located centrally thereof.

Portions of base plate 12 extend above and below slide channel 13 and wire enclosing channel 14 respectively, and these portions of the base plate 12 are provided with apertures 23 through which fastening members such as screws 24 or the like may be extended to mount the base plate 12 with respect to any datum.

Slidably mounted in each end of the slide channel 13 of base plate 12 and extending outwardly therefrom is a hollow bracket arm illustratively rectangular in cross section, as best seen in FIG. 3. The side walls of the bracket arms are slightly recessed to define flanges 27, 28, 29 and 30 extending from each of the corners of each bracket arm 25. These flanges 27, 28, 29 and 30 ride along the interior surfaces of the side walls of slide channel 13 and the flanges 29, 30 also ride along the lips 16, 17 thereof as best seen in FIG. 3 so as to implement free sliding movement of the bracket arms within the slide channel, said arms being retained in fixed position as by set screws 51.

In the illustrated embodiment, a decorative strip 36 is arranged in the recesses between track flanges 27, 30 and 28, 29 to provide a desired decorative appearance for the exposed portions of the bracket arms 25.

The free ends of bracket arms 25 are bent out of the plane of the base plate 12 as shown in FIGS. 1 and 2 and the upper surface of each of such free ends has an internally threaded opening 40 to receive the lower end of an externally threaded hollow stud 35 as shown in FIG. 4.

As illustratively shown, a candelabra type fixture 50 is supported on the free ends of each of the bracket arms 25. Such candelabra type lamp comprises a hollow post 41 having an internally threaded lower end 42 adapted to receive the threaded stud 35. An externally threaded stud 46 is screwed into the internally threaded upper end of post 41 and such stud 46 is connected to a socket support 47 at the upper end of which a bulb socket 48 is mounted.

Where the aforedescribed lighting fixture is used in conjunction with the mirror M of a dressing table, such as shown in FIG. 1, the base plate 12 preferably is affixed to the rear 60 of such mirror as by screws 24 which ex tend through openings 23 in the base plate.

Thereafter, the bracket arms 25 are moved laterally so as to orient the fixture 50 in desired position with respect to the mirror or table which it is intended to illuminate and the set screws 51 are tightened.

Energization of the bulbs in sockets 48 is eflected by means of electrical conductors W which, as illustrated, run from the sockets 48 through the posts 41 into the wire enclosure provided by hollow bracket arms 25 and out through the ends of such arms 25 and through the elongated space 31 between lips 16, 17 of the slide channel 13 into channel 14.

The ends of the wires W leading from the sockets 48 are connected in the wire channel 14 as shown in FIG. 5 to the ends of a conventional electric cord C which extends through aperture 22 and any excessive length of cord C may be pushed into channel 14 for concealment thereof.

Although in the preferred use of the unit herein described, it is aflixed to the rear of the mirror, for example, it could of course be secured to the wall of a room to the rear of the mirror. In such case, it would be merely necessary to reverse the bracket arms so that they extended outwardly from the wall.

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanyin-g drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
